Ford 7.3L Power Stroke (1999-2003) :: P1211 Code With Constant Service Engine Light
Nov 29, 2016
I was on the way back from the weekend trip and got a service engine soon light. I didn't notice any lack of power, rough idle or hard starting cold or hot. So we pushed on home. I checked the codes and it is the P1211.
Doing some research it seems the ICP is not as expected so I hooked up my phone with the Torque app and the IPR and ICP seem to be close to normal at idle and running. I din't see any high IPR %.
At idle the IPR was around 15.5 cold and 10.1 after a short run to the store and back when it warmed up a bit. ICP was around 690-720 cold and 470-490 when i got back.
Does that seem like normal readings? I cleared the codes and the CEL comes back on right away after starting the truck. I do have a TS performance chip that I will take out and see if that could be causing any problems. What else should I be looking into?

I have 2003 f250 7.3 automatic 181,000 miles completely stock. Never had chip,tuner or anything on it. I am second owner and got it when it had 70,000 miles on it. Ok here we go I live on top of a mountain and soon as i start up the mountain or any steep hill, or pull or tow something my service engine light pops on. First time it came on I took it to diesel shop they hooked it up to scanner and said it was code p1211 said icp sensor was bad so they put new one on. Couple days later light started popping back on so i decided to order a auto ingenuity after doing some research.
Hooked up to truck started up mountain while scanning at wot light pops on code p1211 and think it was live data I remember seeing icp pressure at 1922 and duty cycle at 63% i was trying to drive and read it at same time and my lap top went dead. What does this reading mean 1922 pressure/ at 63% cycle done little research but dont really understand. Year and half ago replaced all orings on all injectors, new rebuilt hpop pump. New ipr valve, glow plugs, past month 2 different icp sensor new,and new ipr valve new pig tails on both and light still popping on.

I had a p1211 code when I first got Torque Pro hooked up. I figured it was just because I'd done a couple WOT runs and the HPOP just can't quite keep up with the injectors. I was told this might happen when I ordered the injectors from Gear head. I also noticed that my ICP peaked at around 3600 during one of these runs. I don't have it logged, but I'm certain it was up that high.
The code hasn't returned, but I haven't been running it too hard either. I don't quite know what to make of the ICPs actually being that high. From looking at a bunch of Rich's graphs his doesn't really get past 2800 or 2900. Is this an incorrect reading? Do I need to worry about anything?

My wife returned home and stated that my excursion stopped running twice while she was driving it. She said both times were as she was letting off the throttle coming downhill an off ramp. Both times it fired right up and drove away fine.
I pulled the codes using torque app and it showed a p1211. Unfortunately I had just screwed up my gauge settings so I really didn't have any gauges set up so I couldn't use it. (It's for the 6.0 anyway).
After some Internet searching I am guessing it's an issue with the icp or ipr. How do I tell which one to replace? Truck does have a dp tuner normally set to 80 economy tune.

My truck gave me the p1211 code today. I'm Trying to use dash command to get more info. What should I be monitoring and how do I do it? I'm not familiar with these apps at all?

I have posted a pic of a smoke issue I am having while pulling.
I just pulled a 10,000 lb trailer up a few 7% grades at 8-10,000 ft and the best I could do was 40-45 mph at 6mpg. Every hill would set a P1211 and when the truck downshifted to 3rd the smoke would go away for the most part.
Truck is 100% stock and pulls the same as my F350 with 3.73 gears but smokes a lot more.
The smoke is kind of annoying and performance seems sluggish especially given the 4.88 gearing. Where to start?
Has new ipr, hpop, icp, fuel filter, air filter, fresh 5w40 mobil 1.

I have a 2003 F250CC 7.3 with 200,000 miles on it. I just purchased this truck about a month ago. My question is it blows black smoke. A little at idle but mostly when you give it any pedal. I have replaced all of the injector o rings and that didn't make a difference. Then I had it tested and it failed a CCT test on #2 cylinder. I have an injector to put in it, but am curious to find out if 1 bad injector would be enough to make it smoke all the time. I keep getting P1211 ICP pressure above desired. I had a friend of mine who used to work at a ford garage take a look at it with his computer and he said that everything looks good other than the CCT test.

I bought my 2000 7.3L Ex as salvage back in 2005. It had been through a driver side rollover and the seller had restored it. We lived in North Idaho then. But I remember I always had an issue with the check engine light being on. I don't remember what the codes said, but many mechanics read them and determined that nothing was wrong. Many surmised that someone had put a high performance chip in the computer and that was what was causing the check engine light to come on. All of them reset the computer and every time it would come back on. Should I replace the computer?

So i replaced the faulty injector and the truck starts up great and runs great. The only issue is that now when i accelerate, the SES light comes on until i let it up a little. If i am at cruising speed or just a steady speed the light goes off. I havent checked for codes yet because the light didnt stay on. I have AE and know how to use most of it. Is there something i should be looking at? Could it have something to do with the Blue/Gray CPS i installed or maybe there could still be an air bubble in the oil rail from when i drained the rail ? I have a DP tuner and stage-1 injectors. Regardless it sure is nice to have my truck back out on the road. It was a horrible 3 weeks without it.

Light came on a few days ago. 2000 exc with 7.3 diesel the mileage report said 155000. Took it to Autozone a hour ago and these are the codes: P0683, P0676 and P1670.

Truck started losing power then service engine light came on, drove about another mile then it just stalled ( almost home lees than a 1/4 mile). Got out open hood oil everywhere on top of motor. Looked under truck and oil all over the road. Looked back where I was driving a line of oil as far an I could see. Checked oil barely any on stick. Where should I start hpop or plug?

The SES light in my 2001 7.3 came on about a month ago while I was towing a light trailer in the SoCal mountains. When I got home I spent about 2 weeks replacing the injector o-rings and glow plugs. I discovered while I was in there that the head bolts on the driver's side where loose. I retorqued them to spec.
Both batteries were disconnected for the 2 weeks. When I started the truck the SES light was still on.
My Torque Pro app isn't showing any error codes, and is reading live data correctly. (I didn't have the app when the light first came on; I only purchased it after I finished the repairs). Am I missing something? Is the SES light not necessarily connected to fault codes? If so, wouldn't it reset after 2 weeks with the batteries disconnected?

I have a 2001 F350 and my service engine soon light came on. For a while it went on and off and every time it came on the engine ran rough and I lost some power. I pulled the valve covers and checked the UCVH and everything was fine that I can tell I even made the shims out of quarters and put them in. After putting it all back together its still doing the same thing.

On my 7.3 super cab, I changed the fuel filter last Friday and now on cold start the service engine soon light comes on for a couple minutes (approximately) on a cold start. No other issues. Tried scanning with my scan gauge 2 and no codes. (of coarse I think that thing is a joke for scanning). Not sure if this means anything, but last week before I changed the filter I thought I smelled diesel fuel on a couple different occasions. If I actually did it may not even be related.

So about 3-4 times per day, my truck will accelerate very quickly with the slightest touch of the gas pedal, then followed by the service engine soon light...I checked for any codes to see what I may need to fix, but no codes are found.
What this could be? I am also having issues to where I a few times per day I have to put my truck in neutral to get it to start instead of in park...could the two be related?

I just finished installing a new turbo (shaft play and lots of oil in the compressor side), RR up-pipes, and T500 (250k and once had a very long crank to get the ICP up to start).
Anyway, except for another exhaust leak at the pass side up-pipe to manifold, it seemed to run okay but with lots of white smoke. I only have about 50 miles after the install, when it suddenly starting surging and made a lot of loud knocking noises. This then went away and came back again rather quickly. I was close to home, so I made back under power. I also received the two codes listed. My IPR is original, but two summers ago I installed the IPR re-seal kit. Everything on the IPR looked good when it came off for the T500.
After reading around, I saw that low fuel pressure / air in fuel can cause problems. I connected a pressure gauge to the pre-filter port on the filter housing, and got 40psi at idle. I then took a diesel shower and blew out the fuel line into the tank. After re-connecting it, the fuel pressure stayed the same but the engines idles much better, but still has blue smoke. It's the original fuel pump (to me anyway) and original fuel line connections.
I have about 3/4 tank, and no place to put it, so I'd need to run it out for the Hutch mod, or least to get in there and inspect. Would eliminating the Ford connections at the pump be worthwhile for now, and is 40psi at idle adequate? Wondering if it's time for a fuel pump?

I just bought a 2003 F250 from a used dealer. Unfortunately the service engine light keeps popping on and putting out the code P0401, I have replaced the EGR, cleaned the inside, and cleared the code. However it continues to keep popping up and then it will turn off after a couple of days. I mostly drive in the city and the code generally only pops on when I drive on the highway. I have also noticed a lack or delay of power, when I really hit it hard, I think its because the computer is keeping the egr valve open. What it could be?

Well, long story is that I starting have problems with my 2000 F350 Dually 7.3 PSD about 6 months ago ( ~10K miles ago ). I have sunk almost 5K$ in mechanics and the problem is still present.
By troubleshoot, I do not mean try this, try this, as that has been what is happening. I mean making test measurements and diagnostics. I am fairly mechanically inclined, but I am no mechanic. Looking for primers on how the 7.3 PSD works.
Symptoms: After the truck sits 12 to 14 hours, it starts and idles fine ( ~ 700 RPM on the 'Dash Tach' ) just as it has always done. During the first 5 miles of driving it, the SES light comes on and it sputters, stalls, and vibrates as if a couple of the injectors are not firing. It then clears up and the SES light goes out, except that it idles at about 1200 RPM ( 'Dash Tach' ).
It runs fine like this the rest of the day, If I shut it down it will start right up and run fine, but it has the high idles. Only if it is shut down longer than 12 to 16 hours do the symptoms, other than the high idle, reappear. The high idle is constant. Also mpg have fallen ( 13 opposed to 16 ).
It does not seem to be related to ambient temperature, or the amount of warm-up idle. I have idled it for three hours on startup and it is fine, until I drive the first 5 miles or so.
Now, I have had three mechanics work on it and they have replaced: the ICP sensor ( 3 times ), the Fuel filter ( twice ), drained, flushed and refilled the HPOP, replaced both sides of the valve cover wiring harness, put in a new IDM, fuel heater, CPS sensor ( 3 times ), fuel pump in fuel tank, EBPV ( not sure what this is ), and the last straw was saying the injectors needed to be replaced ( or at least the O-rings, but while we are in there you might as well ... ).
I bought a cheap code reader and it says: P1316 & P1211. I believe these are the same codes since day 1.

The Service Engine Soon light is on in my 2001 F-150. I checked the code and got PO156 generic O2; circuit (bank 2, sensor 2). What are the most common things I should look at? The truck appears to be running fine, no driveability issues.

My Service Engine Soon light came on early last week and I got the code P0442- Evaporative Emission: System leak detected (small leak).
What are the most probable things I should look at?
